Preferably ceramic pigments are It should of course be understood that the employed for this purpose, as the burning of the description and drawing herein contained are ilmatch has the eifect of setting the same. The lustrative merely and that the invention is susimprinting of the concealed indicia is indicated ceptible of embodiment in a variety of forms. at Il. 25

The nature and characteristic features of the After the concealed indicia Il is imprinted on invention will be more readily understood from the match splints I0 the same are coated as at I2 the following description, taken in connection with a suitable material for the purpose of inwith the accompanying drawing forming part itially concealing said indicia. The coating mahereof, in which: terial l2 may comprise various substances, the es- 30 Figure 1 is a plan view, enlarged of a match sential being that the same will either be comembodying the main features of the preferred bustible in the flame of the match, or be disform of the present invention, the same being seminated by the heat thereof, or rendered transshown in its condition prior to ignition and parent by said heat.

The paper of which the splint the metallic oxides, lead oxide and mercurio 45 is made is preferably either of a special compooxide being particularly adaptable, the same besition or is so treated that upon the burning ing applied in a suitable vehicle such vas linseed thereof the same will not be unduly twisted, disoil or the like. If mercurio oxide is used, the torted, discolored, or reduced to a fragile ash. same will be completely volatilized upon the For example, the paper may have impregnated burning of the match, whereas in the case of 50 therein various chemical substances for the lead oxide the same will be reduced to tiny beads aforesaid purpose, such as barium sulphate, magof metallic lead which will permit the concealed nesium carbonate, magnesium oxide, or zinc indicia to be seen, at the same time imparting oxide. Various other substances may also be an ornamental effect of its own.

found suitable for thisV purpose, and in some A concealing coat which has been found to 55 be particularly adaptable may comprise any of the well known mixtures, which, upon the burning of the match. will form a transparent glaze through which the concealed indicia will be visible. v

After the concealing coating I2 is placed on the splint over the concealed indicia, an overprinting I 3 of visible indicia may be placed thereon. The ink or other material employed for the overprinting I3 should be of a combustible type, or capable of being disseminated by the heat engendered by the burning of the match. Aniline dyes in a linseed oil vehicle, or in a. parafiin, wax. or heavy grease body, will be found quite suitable for this purpose, or the metallic oxides may be used in a. suitable vehicle such as linseed oil.

In the use of the match it is only necessary for the user thereof to strike the same in the ordinary manner, whereupon during the burning of the match the concealing coating as well as any overprinting which may be placed thereon will be consumed, disseminated, or transformed, by the heat of the match as the same burns. In this manner the concealed indicia will be rendered visible.

It will be seen that there is provided a. novel form of match which Will be of peculiar value for advertising purposes in that the curiosity of the user will be excited, and in this manner the message conveyed by the concealed indicia will be definitely impressed upon his mind.

It will, of course, be understood that the matches of the present invention may be used for purposes other than advertising; for example. suitable games may be worked out in connection therewith.

It should also be understood that while the invention has only been illustrated in connection with the splint oi the match, the same isl and a coating for initially concealing said indicia which would otherwise be visible, said concealing coating being alterable by the burning of the match so that the aforesaid indicia will be rendered visible when the match is burned.

2. A match having indicia imprinted therev on, a concealing coating over said indicia, said' concealing coating being alterable by the burning of the match whereby the aforesaid indicia will be rendered visible, and an overprinting of initially visible indicia disseminatable upon the burning of the match.

3. A match having the splint thereof treated to minimize distortion, discoloration and reduction thereof to a fragile ash, indicia imprinted on said prepared splint, and a coating for initially concealing said indicia, which would otherwise be visible, said concealing coating being al1- terable by the burning of the match so that the aforesaid indicia will be rendered visible when the match is burned.

4. A matchfhaving the splint thereof preliminariiy prepared to minimize distortion, discoloration and reduction thereof to, a fragile ash, indicia imprinted on said prepared splint, and a coating for initially conceal-ing said indicia which would otherwise be visible, said concealing coating being alterable by the burning of the match so that the aforesaid indicia will be rendered visible when the match is burned.

5. A match having the splint thereof preliminarily prepared to minimize distortion, discoloration and reduction thereof to a fragile ash, indicia imprinted on said prepared splint, a concealed coating over said indicia, said concealing coating being alter'able by the burning of the match whereby the aforesaid indicia will be rendered visible, and an overprinting of initially visible indicia disseminatable upon the burning of the match.
